your premed office should hopefully have a listing of volunteer/internship opportunities in the area, or you can always go onto the websites of various independent or university affiliated hospitals and look for volunteering opportunities. I don't know about any of the cities mentioned but these programs were very easy to find in many new york hospitals. of course, what you will be doing is shadowing or menial things. If your premed office is no help just look up all the hospitals in the area, find their websites or call, and ask about clinical exposure opportunities
